Current Events: Lysosomes - Nature's Garbage Disposals?


Click here for an article from the NY Times about lysosomes. What you think about this article?
What do lysosomes recycle? What is the difference between proteasomes and lysosomes?

  1. you should make it homework to watch house, you can learn allot about all medical science because everything they say is true...

  3. This article is really interesting, especially self-destruction = live longer.
    How ironic. I think it's cool how lysosomes can suck in MITOCHONDRIA.
    Impressive.

  6. Hi everyone!
    Pia - great joke:)
    Huwon - I also think that it is so cool that lysosomes can suck in mitochondria! I wish we could see a video of that occuring.
    Radhika - I've never seen House, so I doubt I will assign it as homework. I will have to check it out this week.

  7. We could have watching House as optional. Maybe it can be on the blog and we can comment on it.

  9. on youtube there is a whole video on lysosomes, and i think they show a lysosome actually sucking in a mitochondria. i still am trying to figure out if one of the clips of the lysosome is actually sucking in a mitochondria. because something is going inside the lysosome. i am not sure???

  10. Hi Leslie! I have a really great video that you should see on Youtube that Dmitry showed us last year. Search "The Inner Life Of A Cell" Choose the first video (it's by Biovisions). The video is really awesome. I think it's really cool how we are learning about cells.

    Ps. i like motor proteins

  11. Oh yeah! the inner life of a cell is a GREAT video! i luv how the ribosomes uncodes the DNA and makes s seperate RNA strand from it, it reminds me of cheese in a can...

    P.S The tune in the Inner life of a cell (music version) is my lullaby! its so relaxing :)
    The motor protiens are soooo cute! This is the music one: http://www.youtube.com/watch?v=BtZEqQ1cpmk

    this is the informational one: http://www.youtube.com/watch?v=fZZ3DD_tV9k&feature=related

  12. In the last part of the article it said that mice who were on diets were better at autophagy and so were more resistent to cancer an other diseases that come with old age. If autophagy helps you become more resistant to some diseases than that could mean the less you eat and the more you are on a diet, the healthier you are in your old age, right? so the less you eat( but don't starve yourself)the longer you live?

  13. I think the lysosome = live longer thing is really cool. What if they inject people with the thing they did for the mice? Could they use that to end cancer? or what if they figured out a way to use it to make people live longer. Tis whole thing is very interesting.

    P.S. What is house?
    P.P.S. I don't think it is fair to make people watch TV for HW, because some people don't have time (like me) or acsess (like me again). My TV has problems. ;)

  14. I think that the article was very interesting, i read the whole thing and i think it is awesome how the mouse's (whose age was the equivalent of an 80 yr. old human) liver started to work like a 20 year old humans liver!
    Also, do you think that this is some kind of breakthrough that could to a cure for some cancers and other diseases????

  15. wow! i think it's amazing that self destruction can cause you to live longer. it is the total opposite of what i thought. i wonder when they will figure out how to use this discovery to end diseases like cancer and altzhimers disease.
    also last year in science we made modles of cells and some people had different types of crystals in their modles; i think some of them were graffite crystals and crystal lattice. does anybody know anything about this?

  16. wow, people are agreeing with matthew about house. you do know that that is all he ever talks about

  17. I found this really cool site about lysosomes.
    it's called...

  18. i never knew lysosomes were such a big part of the cell! with this article, i learned a lot on them! thanks, leslie!

  19. They look so tiny in our textbook diagrams. But then again, just looking at your typical backyard leaf under a microscope can be like looking at a whole other world.

  20. LYSOSOMES are a big garbage dump tom 7g

  21. I kind of agree that lysosomes are self destructive, but I think a better term would be self reusable. They get rid of old parts.
